Hand held appliance

Abstract

Disclosed is a hair care appliance comprising a body, a fluid flow path extending through the body from a fluid inlet to a fluid outlet and a PCB extending about the fluid flow path. The PCB may be annular. The PCB may be isolated from the fluid flow path. The PCB may comprise a first layer and a second layer. The first layer may extend substantially continuously about the fluid flow path and the second layer may extend partially about the fluid flow path. The second layer may be adjacent the first layer and may be downstream of the first layer. The body may comprise a duct and the fluid flow path extends through the duct. The PCB may extend about the duct. The body may comprise a primary fluid flow path extending about the duct which may be in fluid communication with the PCB.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of United Kingdom Application Nos. 1312069.6 and 1312074.6, both filed Jul. 5, 2013, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to a hand held appliance, in particular a hair care appliance such as a hairdryer.BACKGROUND OF THE INVENTION[0003]Blowers and in particular hot air blowers are used for a variety of applications such as drying substances such as paint or hair and cleaning or stripping surface layers. In addition, hot air blowers such as hot styling brushes are used to style hair from a wet or dry condition.[0004]Generally, a motor and fan are provided which draw fluid into a body; the fluid may be heated prior to exiting the body. The motor is susceptible to damage from foreign objects such as dirt or hair so conventionally a filter is provided at the fluid intake end of the blower. Conventionally such appliances are provided...

AI Technical Summary

Benefits of technology

The patent text describes a hairdryer design with several technical advantages. Firstly, the handle is made as a single unit, which makes it more difficult for users to disassemble the product and access its components. Secondly, the design without any joined surfaces, screws, or recesses, makes the product visually cleaner. Additionally, the hairdryer has a primary fluid inlet on more than one surface, which reduces the chance of blockage and damage to the motor. The double layered wall also isolates internal components from external vibration and noise. An insulating material such as foam or felt is preferred to mitigate noise, vibration, and heat produced by the appliance.

Problems solved by technology

The motor is susceptible to damage from foreign objects such as dirt or hair so conventionally a filter is provided at the fluid intake end of the blower.
